.Water heater for beverage maker

The invention relates to a runner f

heater for beverage makers according to the generic term sj

of claim 1. J

I.

S There is already a flow heater for beverage <

ready according to the preamble of claim 1 be | '

where the double tube is roughly horseshoe-shaped |

is bent and the two tubes are on top of each other. 1

The bracket consists of a wire hanger that holds the j

Water guide pipe engages under and from the outside in I

Slits in the legs of the metallic bracket of the | Controller intervenes.

The object of the invention is to provide the water heater mentioned in the preamble of claim 1 Way to improve the attachment of the regulator to the water pipe. |

The object set is according to the invention by I

which in the characterizing part of claim 1 to I

given training solved. |

An expedient further development of the invention

The subject matter is specified in claim 2.

By using a clip made of strip material instead of a clip made of wire, a more stable fastening against changes in the position of the controller is achieved, especially in the longitudinal direction ^! of the water pipe.

An Aüsführüngsbeispiel the invention is shown finely schematically in the drawing. Show it:

Fig. 1 is an elevation of the section having a regulator of a double

tube,

Fig. 2 is a side view along line II - II

in Fig. 1,
Io

Fig. 3 is a plan view of a portion of one formed from a sheet metal strip Bracket.

In the drawing, 1 is an extruded

Double tube, for example, made of aluminum.

The double tube 1 has a web 1 a (Fig, 2) between its tubes.

2o

The one pipe 1b of the double tube 1 is designed as a water supply pipe, while the other tube 1c of the double tube 1 is the casing tube of a t the electric tubular heater. The heating resistor

stand dec electric tubular heater is designated with 2 (Fig.2). The heating resistor 2 is in Surrounded in a manner not shown with a granular insulating material. Di? Pipes 1b and 1c lie diagonally next to each other (Fig. 2).

3o

In the example shown, the jacket tube 1c is polygonal in shape. A surface 1d of the jacket pipe 1c is designed as a support surface for a worm holding plate.

On a flattened point 1e (Fig. 1) of the water

s & rführungsrohres 1b is a regulator 3 with a Clamp 4 attached from spring material.

The clamp 4 engages in a metallic bracket 3 resting on the water guide tube 1b and rests on the water pipe 1b.

As can be seen from FIGS. 1 and 3, the bracket 4 is formed from a sheet metal strip * the has a first longitudinal section 4a extending from one end, which is expediently approximate is as wide as the clear distance between the legs of the metallic bracket 3a of the controller 3. The for Bracket 4 shaped sheet metal strip has a second extending from the other sheet metal strip end Longitudinal section 4b, which is significantly narrower than the first longitudinal section 4a, which, as shown in FIG. 3, two shoulders 4c, 4d are formed at the transition to the second longitudinal section 4b.

2o

The free end of the first longitudinal section 4a of the sheet metal strip forming the clamp 4 is hook-shaped bent and hung in a groove of one I) end of the web of the metallic bracket 3a, as can be seen from the left-hand side of FIG.

f As also from the left side of Fig. 2 he

recognizable is the sheet metal strip forming the bracket 4 first directed away from the water pipe 1b, then towards the water pipe 1b pulled up and from the system on the water pipe Ib to a bed for the water pipe 1b shaped. The shoulders 4c, 4d of the first longitudinal section of the sheet metal strip forming the clamp 4 lie on the side of the bridge 1a of the double

tube 1, which is turned away from controller 3 * the latter results in particularly good lateral stability of the fastening of the controller 3.

The second longitudinal section 4a of the sheet metal strip forming the clamp 4 extends through one of it adapted, but not shown slot of the web 1a of the double tube 1.

Like the free end of the first longitudinal section 4a, there is also the free end of the second longitudinal section 4b of the sheet metal strip forming the clamp 4 is shaped like a hook and in a groove of the web of the metallic bracket 3a hung.

The second longitudinal section 4b of the sheet metal strip forming the clamp 4 can, as can be seen from FIG. 2, bent over on the side of the web 1a of the double tube 1 facing the regulator 3 and then only be bent towards the associated end of the web of the metallic bracket 3a. But it is also possible, the second longitudinal section 4b from the web 1a more or less directly on the associated To align the end of the web of the metallic bracket 3a.
